There are many factors that lead to food waste, making it a difficult issue to solve, even with the existence of the clay fridge. The UN Food and Agriculture Organization estimates 1.4 billion tons of food is wasted every year between consumers in developed countries and supply chain problems in the developing world. While there is no easy fix, the Mitti Cool Refrigerator provides what Co.Exist calls a "stop-gap solution of sorts."

This clay fridge does not need electricity to run and will keep produce and other spoilable foods safer to eat for longer, without replacing a standard refrigerator. Invented by Indian Mansukhbhai Prajapati, the food storage solution is made out of porous Gujarat clay that is eco-friendly and not harmful to human health.
